A study within a UK ambulance study exploring the customs and beliefs or paramedics in relation to airway management and whether tracheal intubation sustains professional identity. Interviews were conducted with 17 participants, which identified four key factors: pride, utility, expectations and professionalisation. Authors conclude the interviews identified a 'wide range of views' on airway management based on evidence and experience.

Data on patients with OHCA and attempted resuscitation in an area of Finland over a six-month period in 2010 was collected, with airway techniques and adverse events recorded. Of the 614 patients, 67% were treated with endotracheal intubation and 30% with supraglottic airway devices. Overall survival to hospital discharge was 17.8%.
